Compositions and methods for remediating chemical warfare agent exposed skin
The present invention relates to chemical and biological warfare agent decontaminating compositions and methods for using the same to decontaminate animal skin and wounds thereon exposed to the agents. The compositions may comprise a peracid, a hydroperoxide, and a peroxyacid.
1. A method of decontaminating an animal wound exposed to a chemical warfare agent, comprising contacting the wound with a decontaminating composition in an amount sufficient to decontaminate the wound, wherein the decontamination composition comprises active decontaminating compounds, and wherein the active decontaminating compounds consist of:
peracetic acid in an amount ranging from about 2% to about 6% by weight;
hydrogen peroxide in an amount ranging from about 3.2% to about 20% by weight; and
acetic acid in an amount ranging from about 2.8% to about 20% by weight.
2. The method of claim 1 , wherein the animal is exposed to a chemical warfare agent selected from the group consisting of a V-series nerve agent, G-series nerve agent, A-series nerve agent, mustard agent, and any combination thereof.
3. The method of claim 1 , wherein the composition is formulated in a form selected from the group consisting of a gel, sol, liquid, lotion, irrigation gel, and spray.
4. The method of claim 1 , wherein the decontamination composition is contacted with the wound by at least one of:
soaking the wound in a solution of the composition,
dispensing a pressurized solution of the composition onto the wound, or
applying a coating or layer of the composition on wound.
5. The method of claim 1 , wherein the animal is a human.
6. The method of claim 1 , wherein the decontaminating composition further comprises a stabilizer selected from the group consisting of etidronic acid, disodium ethyelendiamine tetraacetic acid, ethylenediaminetetraacetic acid, tetrasodium ethylene diamine tetraacetate, citramalic acid, dipicolinic acid, dipicolinic acid N-oxide, and a combination thereof.
7. The method of claim 1 , wherein the active decontaminating compounds consist of:
peracetic acid in an amount ranging from about 2% to about 6% by weight;
hydrogen peroxide in an amount ranging from about 5% to about 20% by weight; and
acetic acid in an amount ranging from about 5% to about 20% by weight.
8. The method of claim 1 , wherein the decontaminating composition is contacted with the wound by:
applying the composition to the wound for a period of time, followed by wiping the site of application to remove the composition.
9. The method of claim 8 , wherein the period of time is 15 minutes.
